448 Miss G. Ricardo — A Revision of 



Scliiuer placed it in the genus Neoitamus, but it does not 

 belong to that genus^ and the species Schiner described in 

 Yerh. z.-b. Wien, xvii. p. 408 (1867), must be an altogether 

 different species from this type, which is apparently an Asilus 

 species, though the sides of abdomen have strong black 

 bristles ; ovipositor small, conical. Legs red, tarsi blackish, 

 fore femora with some black bristles below. Moustache 

 chiefly yellow. 



The type of Asilus trachalus from same locality, a female 

 in a very greasy state, is probably identical with the above. 



Asilus coedicius, Walker. 

 List Dipt. ii. p. 45,7 (1849), et vii, Suppl. 3, p. 735 (1855). 



Type from New Holland (abdomen destroyed) and another 

 female may possibly belong to the genus Eutolmus, but are 

 in too imperfect a state for identification, A small black 

 species, with the tibiae partly yellow. 



Asilus margitis, Walker. 

 List Dipt. ii. p. 461 (1849), et vii. Suppl. 3, p. 737 (1855). 



Tvpe (female) from Melbourne has lost its abdomen. A 

 small black species with tibise dull testaceous. Walker 

 suggests* his Asilus coedicius may be a variety of this species. 



Asilus villicatus, Walker. 

 Dipt. Saund. i. p. 147 (1851), et List Dipt. vii. Suppl. 3, p. 734 (1855). 



The type (a female), from New South Wales, is very 

 small ; the male type mentioned by Walker is not to be 

 found. It was suggested by Schiner that it might be iden- 

 tical with his Neoitajnus melanopugon, now identical with 

 Neoitamus varius, Walker ; this is not the case, and the 

 species hardly seems to belong to the genus Neoitamus. Till 

 further material is available, its correct generic place must 

 be left uncertain. In size and general appearance it seems 

 related to Asilus exilis, Macquart. 



The following three types of INIacquart, seen by me in the 

 Paris Museum, 12. 4. 11, could not be placed in their correct 

 genus either owing to being isolated specimens or because 

 of their state of preservation.
